REMOVABLE COVER.

Application filed June 23, 1925. Serial No. 39,029.

To all whom it may concern:

Be it known that I, ADOLFO C. RIGGS, a citizen of the United States,residing at Covina, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in RemovableCovers, of which the following is a specification.

My invention is a removable cover adapted to be attachedto various sizesof barrels or kegs to form a temporary closure.

The invention pertains to closures or covers for barrels or kegs inwhich produce is displayed for sale and in which it is desired to have acover of neat appearance which will allow'inspection of the goods andwhich will also form a tight cap or covering on the barrel or keg toprevent entrance of dirt, flies or the like.

One of the features of my invention is a clamp adapted to be securedaround the upper rim of the barrel and having a capping v ring extendinginwardly over the top of the barrel. In the device illustrated thecapping ring is of a fixed and standard size,

Whereas the clamping strap is so constructed as to accommodate barrelsof considerable difference in diameter. A lid, preferably formed ofglass, is hinged to one side of the capping ring and is also swivelledto the ring so that the lid may be swung around completely out of theway for filling or cleaning the barrel or container.

My invention will be more readily understood from the followingdescription and drawings, in which;

Figure 1 is a perspective view of my removable cover secured to the topof a barrel.

Fig. 2 is a cross sectional elevation on the line 22 of Fig. 1., showingthe removable cover detached from the barrel.

Fig. 3 is a horizontal section on the line S3 of Fig. 2 in the directionof the ar-' rows, showing the clamping straps.

Fig. 4 is an enlarged detail of a section shown in Fig. 3, illustratingthe manner of securing the glass to the lid ring.

Fig. 5 is a plan of the hinge in the direction of the arrow 5 of Fig. 1,showing the manner of mounting the hinge and the swivel to give twomotions to the lid.

In the illustrations a barrel, keg or the like is designated by thenumeral 1, in which even in standard sized barrels or kegs the upperedge or rim 2 varies considerably in diameter. Moreover, barrels andkegs of different makers differ to such an extent that a fixed ordefinite sized lid does not make a satisfactory removable cover. Theremovable cover is designated generally by the numeral 3 and isconstructed in detail with an 1adjustable clamping strap and a fixedsized The strap 1 comprises right and left sections 5 and 6 secured byclamp screws 7. Each of the sections 5 and 6 are preferably formed ofsimilar straps 8 and 9 having eyes 10 formed by bending the strapsthrough which extends capping ring pins or rivets 11. have outwardlyextending lugs or flanges 12 through which the clamp screws 7 extend. Inorder to allow quick adjustment one of the flanges may have an aperture13 and the other a slot 1 1- so that the clamp screws 7 may be readilyinserted and clamped tight by a thumb nut 15. In this manner theclamping strap is formed of two ,pairof hinged straps connected by a pinso that they may swivel and the two pairs or sets of straps may be drawntightly together to form a tight clamp on. the rim of the barrel. Thisalso adds to the strength of the barrel in handling.

A pping ring 16 formed of preferably a flat annulus of metal ofsufiicient width to cover all the various sizes of barrels to which theclamping strap may be accommodated, is secured to the strap by therivets 11, the connection being sufficiently loose to allow the strap tobe tightened or loosened as required.

The lid designated generally by the nu meral 17 is built up with a lidring 18 having a. vertical flange 19 and a horizontal. flange 20. Asheet of glass or the like, 21, having a rubber or other resilientpacking ring 22 is clamped to the underneath surface of the horizontalflange by means of bolts 23 secured to a stop ring 24. In this manner bytightening the bolts the ring 2 1 may be pressed against the lowersurface of the glass evenly and form a tight closure with the lid ring1.8. a

The lid 17 is provided with a hinge 25 having a fixed plate 26 securedto the lid ring 18 by means of rivets 27 and having a horizontal hingepin 28- connecting the fixed plate with a swivel plate 29. This latteris secured to the capping ring 16 by Each of the sections 8 and 9' 4 i0and means of a swivel pin 30. This pin has suitable heads to allowswivelling of the lid on a vertical axis and also allows the lid to befolded backwards on the horizontal pin 28. Nhere merchandise such asfruit or the like can be removed from the barrel with one hand it ismore convenient to raise the lid on its horizontal hinge, but if bothhands are required such as removing butter from a butter tub it is moreconvenient to swivel the lid on the vertical swivel pin. The hinge maybe arranged and the swivel pin so positioned that when swivelled the lidwill hang downwardly alongside of the barrel or tub and thereby be outof the way.

T he particular construction of my removable cover may be considerablychanged to adapt it for use with different materials. The constructionshown is formed with a metal frame but a wood construction could readilybe adapted for the purpose and have the same general characteristics.Moreover, my device may be adapted to cover square or rectangular boxesor other irregular shaped containers. Thus, various removable covers maybe made in accordance with the spirit of my invention having a clampingdevice which may be accommodated to various sizes of containers withinreasonable limits and having a fixed capping ring or the like to form aclosure on the top or" the container with a lid attached thereto.

Having described my invention, what 1 claim is: p

1. A removable cover comprising in combination a plurality of flexiblestraps connected in pairs, pins forming a pivotal con nection for saidpairs of straps, clamping screws connecting each pair of flexible strapstogether, said straps and connectlons allowing the straps to be clampedto various sized containers, a fixed sized capping ring secured to saidpins, said ring comprising a horizontal flat annulus and a lid connectedto the capping ring and adapted to be opened or closed.

2. A removable cover comprising in combination a plurality of flexiblestraps connected in pairs by means of a pivotal connection, clampingscrews connecting each pair of flexible straps together, said straps andconnection allowing the straps to be clamped to various sizedcontainers, a fixed sized capping ring secured to the clamping straps,said ring comprising a horizontal flat annulus, a lid, a hinge having afixed plate secured to the lid, a horizontal hinge pin, a swivellingplate connected to the pin and a vertical swivel pin through the swivelplate connecting the swivel plate to the capping ring, said swivel. pinbeing positioned whereby the lid may be swivelled vertically and hingeddownwardly to hang along the side of the container.

3. A removable cover comprising in combination a clamping strapcomprising two pairs or flexible strap elements, said elements having aneye and a pivotal pin therefor, the free ends of said strap elementshaving flanges and clamp screws engaging said flanges, a capping ringcomprising a horizontal flat annulus connected to the said pivotal pinsand a lid hinged to said cap- I ping ring.

4. A removable cover as claimed in claim 3 having in addition a verticalswivelling connection between the hinge and the capping ring whereby thelid may be swivelled on a vertical axis and hinged downwardly along theside of the container.

In testimony whereof I have signed my name to this specification.

A. G. RIGGS.
